Yes, I do recall hearing that Nemo single a LOT on radio as a kid but amazed it didn't chart. In fact, I've never actually encountered a copy of the actual single. Seems to be one of those airplay hits that for some reason or other didn't translate to chart success yet many think it was a hit!
I have you to blame JK for my Mum's party piece... it's singing the song with the words reversed so it comes out like "Eht nus sah tog sih tah no... pih pih pih yarooh!"
It sits nicely alongside her Cilla Black, Barry Gibb and Meat Loaf impressions... and those impressions are deadly funny and accurate too!
That "Hit Millionaire" album (where we finally got the song) was a life changing album that my family played heavily, sang along to and generally had great fun with. I'm happy to report that though my parents divorced many years ago, I did rescue that album and still have it complete with that gold flexi. Great album.
